1 FOOTBALL GOAL POSTS BACKGROUND AND SUMMARY OF vTI-IE INVENTION This invention relates to football goal posts and eliminates their tendency to be both a safety hazard to the player and an obstruction-to the flow of the game.

A goal post isused as a scoring target for field goals and extra points in a football game. The conventionally used goal post consists of a U-shaped target comprising a horizontal cross-bar and two vertical uprights located at the opposite ends of the horizontal cross-bar, and a ground-anchored vertical member affixed to the U- shaped scoring target to support it at a fixed, predetermined vertical distance above the ground.

A football playing field is laid out so as to include a goal line which represents the touchdown scoring marker and an end-zone extending for ten yards behind the goal line. The end-zone is part of the playing field and the area behind the end-zone is out-of-bounds. A substantial amount of play during a game takes place in the end-zone area.

In professional football, the goal post is constructed so as to have its ground-anchored vertical suport member located in the end-zone two or three yards behind the goal line and its cross-bar and uprights located in a vertical plane extending upward from the goal line. Therefore, the goal post is a fixed obstruction placed in the midst of the playing area.

This conventional goal post construction is both a safety hazard to the players and an unwanted obstruction to the flow of the game. The presence of groundanchored supports in the middle of the end-zone presents a serious hazard to the players on the field, because if a player runs into a support member at full speed he is liable to suffer serious injury. This hazard is especially dangerous to a defensive back who is easily led into the ground support by a receiver; it is also very dangerous to a receiver who can crash into a support because he must keep his eyes on the ball.

Furthermore, the location of the ground support in the middle of the end-zone interferes with the patterns of play in the game. For example, the ground support can be an obstruction to a'receiver running his designated pass pattern and can upset the precise relationship between the quarterback and the receiver.

The uprights and cross-bar also obstruct the normal flow of the game because they are located in a plane extending directly over the goal line at a relatively low distance from the ground. Because of their location the uprights and cross-bar present a blocking surface against passes directed at a receiver located in the endzone. It is not unusual for an end-zone directed pass to hit either the cross-bar or the uprights and, of course, if such a deflection occurs the play is unnecessarily-obstructed. These members also present a blocking surface to a punter attempting to kick the ball out of the end-zone.

The goal post is only used when the offensive team is either kicking a field goal or an extra point; therefore, it is not necessary that it be in its target position over the goal line at all times of play and, in fact, at all other times a goal post hinders rather than assists the play of the game. It is an object of this invention to eliminate both the afore-mentioned hazardous and obstructive character of the present goal post by allowing the goal post to be moved out of target position when it is not needed.

A further shortcoming in conventional goal posts is that the fact of the success or failure of a field goal or an extra point attempt must be determined solely by the visual judgment of the referee. The judgment factor includes the possibility of an error which could vitally affect the outcome of a game. This shortcoming arises because the uprights contain no way of registering a score in response to a ball passing through and it is an object of this invention to provide a means for automatically registering a successful score.

In accordance with the present invention, a goal post is provided which overcomes all of the aforementioned difficulties. This goal post is anchored behind the end-zone in a position where it presents no real safety hazard to the players. The uprights and cross-bar can be pivoted out of an obstructing'position when they are not needed as afield goal or extra point target. Furthermore, the goal post includes a detector for registering a successful field goal or extra point which is activated by the football passing through the uprights.

In the embodiment of the invention disclosed herein, the goal post comprises a ground-anchored vertical support member and a pivotably attached upright and cross-bar boomextending toward the goal line and of sufficient length to allow the vertical support member to be planted in a non-hazardous position. A conventionally U-shaped cross-bar-and upright configuration is located at the opposite end ofthepivotable boom. When the boom is in its lowermost position, the crossbar and uprights are in target position for field goals and extra points; however, when a target is not needed, the boom and cross-bar and uprights can be pivoted upwardly into a non-obstructing position.

The embodiment disclosed herein also includes a se-- ries of photocells on the inner face of each vertical upright. These photocells create a unidirectional photocell field which will be tripped by a football passing through the uprights from the field, but not by an object passing through the uprights in the opposite direction.

Other features and advantages of the invention will be apparent from the following description and claims and are illustrated in the accompanying drawings which show structure embodying preferred features of the present invention and the principals thereof, and what is now considered to be the best mode in which to apply these principles.

BRIEF DESCRIPTION OF THE DRAWINGS DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows the goal post and its relationship to the playing field. The vertical support member 10 is anchored at a safe distance behind the end-zone line 11. The support member 10 is preferably constructed of force resistant material, such as, a steel I-beam. The support is surrounded by a cushioning and protective shield 12 around its base to give some added protection to the players and to protect the goal. post from vandalism by the spectators to a game. A pivot support 13 is affixed to support 10 at about the required crossbar height and contains boom pivot 14. An upright and cross-bar boom 15 is pivotably connected to pivot support 13 and vertical support 10 by boom pivot 14. The upright and cross-bar boom 15- is of sufficient length to extend from the support 10 to a position directly over the goal line 11a when in its lowermost position. The upright and cross-bar boom 15 is pivoted upward through the operation of a motor 16, located at the top of vertical support 10, acting on a steel (or equivalent) tension cable 17 affixed to the boom 15 at point 18. In the present embodiment, the motor is 5 hp. and is arranged for a cable speed of 60 fpm.

The uprights and cross-bar are affixed to the free end of boom' 15.

FIG. 1 shows the boom 15 in its upright position 15' n and demonstrates how when not required as a target the uprights and cross-bar can be moved to and kept in a nonobstructing-location.

FIG. -2 shows the U-shaped cross-bar and uprightconfiguration in greater detail. Cross-bar 19 is fixed horizontally at the free end of boom 15; it is of standard regulation length and when the boom is in its lowermost position is ten feet above the goal line 11a. Uprights 20, 21, which can be in the form of elongated rectangularly cross-sectioned thermoplastic bars, extend vertically from the opposite ends of cross-bar 19 and can be of any desired height. In fact, the uprights of the present invention can be longer than those in conventional use to heighten the detection feature that will be subsequently described.

FIG. 3 discloses the inner face of upright 20 which contains two rows of photocells 22 and 23. The inner face of upright 21 (not shown) contains a corresponding array of photocells. The photocells are wired according to conventional methods so as to create a unidirectional photocell field system that will detect a football traveling from the playing field through the uprights. A football passing through the target will trip the field in proper sequence and activate the scoring register, exemplified in FIG. 2 at 25. The field is arranged so that an object traveling in the opposite direction will not activate the scoring register.

The response of the scoring register 25 can be delayed to accomodate the situation wherein the football passes through the uprights and then hits one of the members and bounces back toward the field; this would not be a score andwould notr egisgr as o ne.

The goal post constructed according to the present invention would'operate in game conditions as follows:

1. the pivotable boom l5 normally would be positioned in its uppermost position where it does not obstruct the flow of the game;

, 2. when cross-bar and uprights are needed for a field photocell field is activated and the score is registered and if it does not pass through the field, of course, no

goal or extra point attempt the boom can be activated from the fieldand lowered to its target position;

'3. if the kick passes through the uprights, then the score will be registered; and

4. after the kick attempt the cross-bar and uprights can be pivotably raised-back to their non-obstructing position.

Thus, while preferred constructional features of the invention are embodied in the structure illustrated herein; it is to be understood that changes and variations may be made by those skilled in the art without departing from the spirit and scope of the appended claims.
